Soft foundation embankment construction method
The invention relates to a soft foundation embankment construction method. The method comprises the following step of packing soil on a roadbed and conducting compacting to form an embankment main body, and before the formation of the embankment main body, further comprises the following steps: 1, constructing a drainage system: digging drainage ditches and water collecting wells for collecting water in the drainage ditches on two sides of the roadbed, wherein the water collecting wells are provided with an inverted siphon used for discharging water in the water collecting well into a local water system; 2, conducting draining: draining water of the roadbed to a drainage system; and 3, conducting original ground treatment: removing the surface layer of the roadbed, then carrying out in-situ curing to form a surface hard shell layer with the thickness of 95-105 cm, and building an embankment main body on the surface hard shell layer. The in-situ curing method specifically comprises the following steps: adding cement and a curing agent to the roadbed, and stirring the roadbed. According to the soft foundation embankment construction method, the stability of an embankment built on a soft roadbed can be good, and the problems that an embankment built on a soft foundation through an existing method is prone to sedimentation and poor in stability are solved.
本发明涉及一种软弱地基路堤施工方法，在路基上填土压实而形成路堤主体，在形成路堤主体前还包括以下步骤：第一步、排水系统建设：在路基两侧开挖排水沟和收集排水沟内的水的集水井，集水井设置有用于将集水井内的水排入地方水系的倒虹吸管；第二步、排水：使路基的水排到排水系统；第三步、原地面处理：对路基清除表层后进行就地固化而形成厚度95厘米～105厘米的表面硬壳层，路堤主体建筑在所述表面硬壳层上；就地固化的具体方法为：添加水泥和固化剂到路基上后对路基进行搅拌。本发明旨在提供一种能够使得建筑在软软路基上的路堤的稳定性好的软弱地基路堤施工方法，解决现有的方法在软软地基上建筑出的路堤易沉降和稳定性差的问题。
